Abstract Details

Purpose:

To assess macular edema evolution after vitrectomy for diabetic retinopathy complications other than macular edema.

Setting:

RETINA CENTER Eye Clinic Iasi, Romania.

Methods:

Prospective, interventional study on persistent macular edema evolution after vitrectomy for complications of diabetic retinopathy other than macular edema. Outpatient 23G vitrectomy was performed in all cases. Eligible cases were considered persistent macular edema accompanying surgical pathology as preretinal and/or vitreous hemorrhage and retinal detachments. Cases with macular edema treated in the last 6 months by laser and/or anti-VEGF or due to taut posterior hyaloid were excluded. Triamcinolone acetonide was not used intraoperatively. Clinical and SD-OCT evaluation was performed before surgery (if possible) or immediately after surgery and at 1, 3 and 6 months after surgery.

Results:

On the 17 cases eligible, 11 cases (64.70%) showed significant improvement after vitrectomy in both macular clinical aspect and central macular thickness. This improvement was slightly evident at 1 month, obvious at 3 months and stable at 6 months after surgery. No rebound of edema was noted in these cases. If visual acuity improvement at 1 month after surgery can be correlated only to main surgical indication, the improvement of vision with 2 lines in 7 out of 11 cases (63.64%) between months 3 and 6 is highly related to progressive macular edema resolution.

Conclusions:

These data suggest a positive impact of vitrectomy on majority of accompanying persistent diabetic macular edema without vitreomacular traction. Unfortunately, vision gain did not paralleled with resolution of macular edema in more than 1/3 of these cases.
